Profits at Samsung's chip business doubled to almost $2 billion - the highest in three years. But smartphone sales growth is slowing sharply, and Samsung expects prices to remain flat. Competitor LG Electronics has seen its mobile unit slip into the red. And sources say Taiwan's cash-strapped HTC has shut down at least one production line.
